Also name bindings documentation file according to the compat string being documented. As a side effect of this change all currently supported/used compat strings are listed while no while card compat string is documented. This, in my opinion, is desirable as only supported hardware should be documented. Signed-off-by: Simon Horman Reviewed-by: Rob Herring --- Based on v5.3-rc1 Tested using: ARCH=arm make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/spi/renesas,hspi.yaml v2 - reference spi-controller.yaml# and thus do not document #address-cells and #size-cells properties. These properties are still listed as required. - Drop comment regarding pinctrl properties. These are not needed as only one state, "default", is supported - Document clocks and power-domains properties. The clocks property is required. Add these properties to the example. - Drop unnecessary interrupt-parent property from example. --- .../devicetree/bindings/spi/renesas,hspi.yaml | 57 ++++++++++++++++++++++ Documentation/devicetree/bindings/spi/sh-hspi.txt | 26 ---------- 2 files changed, 57 insertions(+), 26 deletions(-) create mode 100644 Documentation/devicetree/bindings/spi/renesas,hspi.yaml delete mode 100644 Documentation/devicetree/bindings/spi/sh-hspi.txt diff --git a/Documentation/devicetree/bindings/spi/renesas,hspi.yaml b/Documentation/devicetree/bindings/spi/renesas,hspi.yaml new file mode 100644 index 000000000000..c429cf4bea5b --- /dev/null +++ b/Documentation/devicetree/bindings/spi/renesas,hspi.yaml @@ -0,0 +1,57 @@ +# SPDX-License-Identifier: GPL-2.0 +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/spi/renesas,hspi.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Renesas HSPI + +maintainers: + - Geert Uytterhoeven + +allOf: + - $ref: spi-controller.yaml# + +properties: + compatible: + items: + - enum: + - renesas,hspi-r8a7778 # R-Car M1A + - renesas,hspi-r8a7779 # R-Car H1 + - const: renesas,hspi + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + maxItems: 1 + + power-domains: + maxItems: 1 + +required: + - compatible + - reg + - interrupts + - clocks + - '#address-cells' + - '#size-cells' + +examples: + - | + #include + #include + + hspi0: spi@fffc7000 { + compatible = "renesas,hspi-r8a7778", "renesas,hspi"; + reg = <0xfffc7000 0x18>; + interrupts = <0 63 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&mstp0_clks R8A7778_CLK_HSPI>; + power-domains = <&cpg_clocks>; + #address-cells = <1>; + #size-cells = <0>; + }; + diff --git a/Documentation/devicetree/bindings/spi/sh-hspi.txt b/Documentation/devicetree/bindings/spi/sh-hspi.txt deleted file mode 100644 index b9d1e4d11a77..000000000000 --- a/Documentation/devicetree/bindings/spi/sh-hspi.txt +++ /dev/null @@ -1,26 +0,0 @@ -Renesas HSPI. - -Required properties: -- compatible : "renesas,hspi-", "renesas,hspi" as fallback. - Examples with soctypes are: - - "renesas,hspi-r8a7778" (R-Car M1) - - "renesas,hspi-r8a7779" (R-Car H1) -- reg : Offset and length of the register set for the device -- interrupts : Interrupt specifier -- #address-cells : Must be <1> -- #size-cells : Must be <0> - -Pinctrl properties might be needed, too.
